Abstract: A system and method for improving media delivery and display. By utilizing a memory buffer in a DVR or similar device, and broadcasting linear content at a rate other than 1×, services like video on demand or regular broadcasters can be more versatile. For example viewers can start over without launching a separate VOD session. If part of the linear content requested is not in the buffer, a switched multicast stream can be sent to with the proper section of content. Other receivers on the network may also receive the stream and buffer the content if the content is related to what a viewer is viewing.

Abstract: Techniques for influencing power consumption of a client while streaming multimedia content from a server over a network are described. The power consumption is influenced by controlling how many requests are used by the client to receive media segments of the multimedia content from the server. For example, the number of requests is reduced by increasing the durations of the available media segments. Thus, rather than requesting a certain number of media segments each of a particular duration, a lower number of media segments is requested where the requested media segments have longer durations. Although a longer duration generally results in a larger power saving, the length of a requested media segment is balanced against other parameters associated with current conditions of the client, server, and/or network to allow for, for example, adaptive streaming. As such an optimum duration is determined based on different parameters associated with the current conditions.

The recovery data may be determined based on an original manifest of the multicast data, such as a bitmap or other representation, and the device may generate a recovery manifest indicating the recovery data and send the recovery manifest to the second AP.

Furthermore, the restructuring is performed while maintaining support for pre-existing immutable metadata. Other embodiments, aspects and features are also disclosed. The content remains immutable from the perspective of the end user, but still may be advantageously restructured to optimize storage efficiency.
